Description
Technical field
This utility model belongs to technical field of medical instruments, especially relates to elbow joint.
Background technology
When because of rheumatism, morphotropism joint or wound equivalent damage elbow joint, the function of elbow joint is made to lose
Lose, may feel that violent pain simultaneously.In this case, in order to recover elbow joint function, need
Carry out artificial elbow joint replacement operation.Existing artificial elbow joint prosthese is entirely by reference to the solution of human elbow
Cut open shape, mainly include humeral component and ulna assembly, although meet the daily behavior motion feature of human body,
But humeral component and the initial stability of ulna assembly and combination stability are the highest, and stress is unreasonable,
Cause Elbow replacement prosthese the longest for service life, and existing artificial elbow joint cannot be according to different sick
The skeletal size of people is finely adjusted whole.Accordingly, it would be desirable to a kind of safe and stable life-span length and energy are sized
Elbow replacement prosthese.
Summary of the invention
In view of this, this utility model is directed to elbow joint, to improve Clinical practice safety and to stablize
Property, extend the service life of elbow joint, increase the motility that elbow joint uses.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
Elbow joint, including humeral component, ulna assembly, axle portion, screw thread, cushion and bone bar, described
Humeral component and ulna assembly are flexibly connected by axle portion, described humeral component and the free end of ulna assembly
Being respectively equipped with screw thread, described humeral component and ulna assembly to be connected with bone bar by screw thread, described bone bar sets
The internal thread hole with threaded engagement, the junction of described humeral component and ulna assembly is had to be provided with cushion.
Further, described humeral component, ulna assembly and bone rod outer surface are anti-skidding frosting.
Further, described cushion is elastic abrasion-proof material.
Further, described bone pole length scope is 5-15cm.
Further, the material of described ulna assembly, humeral component and bone bar is Ti-6Al-4V.
Further, the material of described cushion is high hinge ultra-high molecular weight polyethylene.
Further, described axle portion is CoCrMo alloy sliding axis
Relative to prior art, elbow joint described in the utility model has the advantage that
Artificial elbow joint initial stability of the present invention and combination stability are high, are provided with cushion and make it
Reasonable stress, extends the life-span that Elbow replacement prosthese uses, and artificial elbow joint can be according to different sick
The skeletal size of people is finely adjusted whole, improves the safety and stability of Clinical practice.
